Application filed August 7,1926. Serial No. 127,848.

ject of this invention is to construct an ex-. tension member of thischaracter so that it will permit a yielding extension of the bracelet ina direction of its length to permit the same to be passed over the handof the wearer without detachment of any of.

its parts.

A further object of the invention is to provide in such an extensionmember a means for detachably connecting one of the ends of the braceletstrap whereby the same may be detached to form the extension member toremove the bracelet from the wrist.

With these and other objects in view, the invention consists of certannovel features of construction, as will be more fully described, andparticularly pointed out in the appended claims.

In the accompanying drawings:

It isfound in bracelet constructions, which are especially adapted for wristwatch bracelets, desirable to provide a device interposed between theends of the which the effective working e bracelet, for holding thewatch snugly to the wrist of the wearer, maybe yieldingly extended topermit the bracelet to be passed over the hand of the wearer bracelet bywithout detaching any of the parts from each other or from the watch. Itis also found desirable to provide a construction by tached from theextension device to permit the watch to be taken from the wrist withoutpassing the same over the hand oi the wearer, and to accomplish this Ihave provided a spring pressed cross head slidable in the device towhich one of the bracelet parts may be detachably connected and thefollowing is a detailed description of the present embodiment of theinvention showing parts may be. de- I one construction of extensionmember by which these advantageous results may be accom lished.

Wit reference to the drawings, 10 designates the wrist watch havingbails 11 to which strap parts 12 and 13 may be attached. An extensionmember 14 is suit-.

ably interposed between and connected to the opposite ends of thesestrap parts, and comprlses a bottom section 15 having side walls 16formin the same substantially trough shape "an in which is mounted adeckplate posed slots- 18 tl'lBIGHL- Beneath the deck plate there isslidably mounted a cross head member 19 which has pro ections 20extending through the slots 18 to be guided therein.

A spring 21 tends to move the cross head so that thestrap part connectedthere con- 17 having longitudinally disv tracts the size of thebracelet. A top section 22 is hingedly connected to one end of thebottom section and has side walls 23 to telescopingly engage the sidewalls 16 of the is retained in closed position by friction between thesame. A pin 24 extends through the openings 25 and 26 in the bottom andtop sections to hingedly connect them together and also passes throughan opening 27 in the end pleceby said cross head-exten a top platehinged to said section to close permit such action.

other strap part 13 which has opening? 30 to receive the projectionsorpins 20, it mg understoodthat the closing'of the top section 22 over thebottom section engagesthe end of thepins 20 or is-in 'such close prox--imity tothe ends of theprojections 20 that 'the end piece as; isprevented from disengagement with the projections. See Flgures 8. and12, which illustrate the relative posrtion of the to; section to theprojections on the cross hea From the foregoing watch bracelet stra mabe yieldingly extended in the direction 0 this length against thetension'of the spring 21 to enlargethe size of the bracelet to permit itto be passed over the hand'of the-wearer, without detachin'g any of itsparts however, if it isdesired to remove the bracelet without .passingthe same over the hand of the wearer'thetop section 22 may be opened andthe. strap art 13 disengaged from the cross head as illustrated indotted lines in Figure It will also be seen that by mas of the.ilpringfor drawingbzhe strap .part 13 into e ext ension inem r that thebracelet is automatically contracted and will snugly fitawristofanysize, The foregoin description is directed solely towards tieconstruction ,illustrated,
